To all lwhom z't may concern:

Be it known that- I, WILLIAM A'. LORENZ, A

a citizen of the United" States, residing in Hartford, in the' county of Hartford andA "State ofl Connecticut,- have invented. certain new and useful Improvements in Paper-Crinkling l achines, o fwhich the following isa specification.

- This invention relates to anapparatus for crping paper, and particularly to means `for advancing the paperagainst a doctorblade or crinkling element.

'lt has been usual to run the moistened paper over a rotating cylinder, excessive moisture being pressed out of the paper by means of a roll, the roll also causing the paper to stick tothe surfacel of the cylinder.

The cylinder has therefore been enabled to.v

drive the paper edgewisewith considerable `force against the doctor-blade whereby ithas I been crushed or crinkled and also stripped from the cylinder.

One of` the objects of the `present inven` tion is to'provide for successful crinlrling of the paper even though not saturated by moisture, and even though the paperis only suiciently dampened to cause it to adhere slightly to the rotating cylinder, or not v dampened at all, or in case the paper ,is

heavy and stil and hence not Well adapted y' P to bend around and adhere tothe cylinder.`

lt will .be understood that the stine of the paper rendersl it inapt` to stick to the *cylinder and inclines it .to assumea straight form, and hence to separate itself from thecylinderj while, `owing to thisstiness, the resistancel 'of the paper being Vcrinlrlecl,

" is increased." mln other (words, the grip. oity the cylinder on the paper is diminished, while thelneged .arises for crushing the paperwi-th greater force against the doctorblade. p

ln overcoming this diiiculty, there is pro vided anendless driving belt, preferably ot greater breadth than the web that is to be Vcrinkled; and this belt isarranged to 4run around the cylinder from the introductory side-thereof to the doctor-blade, and to conne the webtightly against the cylinder and "crush it edgewise with .force against the doctorfblade, thereby successfully crinlrling comparatively dry paper, as well as slightly or moderately moistened heavy paper. The

tendl into the bightbetween the cyllnder and thebelt, as the latter in leavin the driving power of the belt may be exerted substantially'up to the point where the latter begins to crinkle a einst-the docyadvancing edge of the doctor-blade may exl the I cylinder runs over a guide-roll; and enge tof tor-blade, whereby a forcib e delivery of.

the paper against the doctor-blade is as sured.

Another feature of the inventionA relatesI y to forming figures or other ornamentation upon the crped paper. `This may be done at the same time as the crinkling, and may. be effected by forming intaglio or recessed designs upon the belt, which may be of suitlable,.strong, tough material. 'lhe portions' o l the paper whichv overlie the intaglio des1gns are not crinkled inthe same manner nor to the same extent as the Iother portions @lll byte form araisedy design upon the pa- @ther features and advantages will hereinafter appear. V

n Figure l is a plan of crinkling machinery` embodying the present improvements.

Figure 2 is a sectionalelevation thereof, taken. at about the line 2 2, Figure l.

Figure Sis an elevation drawn upon a larger scale, and represents a section of. the

machine 4taken about "the line. 3-3, Figure l.

- Figure d is a sectional elevation to illus.- trate the mounting of the ,ends of the belt roll at the doctor-blade,l and illustrates how this roll ,constantly presses the bolt against the paper on the cylinder. This ligure also shows means for closely adjusting thisI belt roll relatively to the surface of the crinklin cylinder.

l igure 5 illustrates a design formed in intaglio upon the belt, to produce corre- Ios l spondin desio'ns upon the crinkled paper.

The wgeb msiybe supplied in the form of a rollllO, mounted upon a spool 11 and re tarded by a weighted stra or brake 12. The paper is led over an i le roll 13, and thence around a main cylinder 14; the paper being moistened or steamed upon one or both sides by means of sprinkling pipes 15, 16. The paper in passing downwardly between the rolls 13, 14, comes under lthe control-of an endless beltI 17, which holds the aper to the cylinder until the paper reac es. the vdoctor-blade 18, the latter ad- 'ustably mounted by lbolts 19 upon a cross ar "20, and having a smooth edge to engage the smooth surface of the main cylin-A der,l and an angular front face. From the cylinder the endless belt returns over rolls 22, 23, 2 4. The belt may be tightened by swinging the roll 22 to the left at Figure `2,.this.roll being mounted upon a pair of arms 25, journaled upon a lixed shaft 26 and having a split hub and bolts 27 for fasten- Ita ing the arms where adjusted, to secured and maintain the tautness of the belt.

VThe main crinkling cylinder 14 may be driven by a pulley 28, having a pinion29 to mesh with a. cylinder gear 30; and the roll 21, which may be utilized to perform an important function in the crinkling operation, may be power-driven by means of pinion 31, fixed upon vroll shaft 32 and meshing with the main gear 30.

, sfthel web of pa r runs oil' from the spool '11, and over t e roll' 13, it may bg moisteneds by water or steam on one or sides, and from the roll 13 passes down between the belt 17 and the main cylinder or other carrier 14. The belt drives the paper -around the cylinderto and againstthe doctor-blade 18, and crinkles the paper as indicated at` 33; 'the crinkled aper being Idelivered fromthe machiner y a belt mechanism. 34.-

The roll 21 may be placed so near the doctor-blade 18 that the control offthe paper by the driving belt/may be maintained up to the point where the pa r actually bes to crush against the, lade, especially if the latter be so inclined as to enter the bight or space between the roll 21 and the cy inder 14, shown at Figure 3. By means of the-adjustment seen in Figure 4, the roll 21 mayA be set as closely as desired to the cylinder 14, so as to insure the desired control of theadvancing paper. The roll shaft 32 extends through a bearin or box 35 at each end of the shaft, said aring being supported upon a screw 36, to rinit fine up-and-down adjustment of the s aft, thereby to regulate the closeness ofthe roll 21 to the main cylinder 14; and compression spring 37 may be ad'usted by screw 38 against the block 35, to old the latter firmly down upon the .screw 36 at each end of the roll; the screw 38`being secured by a nut 3 9. Thus xactly the right relation may be .securedtween the -rolland the main C, linder, and the machine is readily adapta le to ditferentkindsand thicknesses of paper. The paper maybe driven along by reason solely of the tautness of the belt holding it against the cylinder 14, or partly by reason `of the tautness of the belt and partly by reason of the pressure of the springs 37, which. may hold the rolll down with force against the belt and paper; this result being secured by adjustment of the screws 36. The doctor-blade ma be placed at differentV angles, and may inserted more or less into the bight between the rolls 21 and 14, according to the requirements of the work to be done. belt alone may be relied upon in some cases to carry the paper against the doctor-"blade, and the latter may be set as close as desired to roll 21 Sand the belt thereon.

It desired, the belt may be Vformed with intaglio designs or depressions 40, Figure 5, upon the face thereof next to the paper, so that corresponding designs will appear in the crinkled paper deliveredy from the ma-' the ybody-portion of the paper, so that the designs will become Lprominent and attractive. For forcing the crinkling paper into the designs, the blade 18 may be set more closely towards the roll 21 than shown in the drawings, if desired. The belt maybe made of leather, rubber, metal or any preferred material.

The roll 24 may also 4be provided with adjustable springs 37V and set screws 36 and bearings-35, if desired.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be 4used. withoutothers. Having thus described my invention, I claim: i'

1. A. paper-crinkling machine comprising, in combination, a mam cylinder or carrier, a' doctor-blade therefor, an lendless"be1t to run partly around the'cylinder to the'doctorblade, and means Afor leading the paper tojthe belt and cylinder to be driven thereby against the doctor-blade, intaglio designs being formedl u on said'belt, for producing corresponding esigns or effects 'in the crimped web. y

2. The combination with a doctor-blade or crinkling` element, of means to co-operate therewith for producing a compound design upon paper, including means to advance the paper to the doctor-blade or The tautness of the mesme crinkling element, and means provided np-` guide-roiis for guiding the beit on the cylinon said advancing means, for controlling dei* and of the cyiinder, the belt being pro- 10 an element of the compound design.

3. The combination of a cylinder or car-A Iier, a belt for carrying the paper on the cylinder, means for advancing the paper with the cylinder and belt, a doctor-blade against which the paper is crinkled, and

vided y"with recesses in designs for forming designs or eiects on 4the crnkied fabric.
